11- Claims. (Cl. 160-369) Window screen in'position on a window frame, said means exerting, at all times, bothY an inwardy and a downward pressure so that the screen frame maintains tight Vfacial contact with the face of thewi'ndow frameY and is firmly locked in position thereon to'eliminate rattles caused' by high winds Iand toA also exclude bugs and insects of all kinds.

Another' object is to provide stationaryl supporting brackets on the window frame and provide interrelated means on the screen frame for yielding releasible engagement therewith, said screen frame being subject to yield-1- ingvertical movement while thus held.

A furtherobject is toprovidenovel locking means on the lower rail' of the screen frame, lockingly engageable With the window frame, said locking means being readily releasable fromV the window frame when upward pressure is applied to the screen frame.

Still a further object is to provide a screen frame which can be easily and quickly mounted and/ or removed, said mounting permitting the lower edge of the screenl tobe twung `outwardly for repair, cleaning, painting, replacement, shaking-mops, or for any other purpose.

A still further object' is to provide simple and substantial hardware which can be readily located and secured in position on thescreen frame, all kof which can be economically manufactured and assembled, and'whilch lends *itself to quantityl production with the savings incident thereto.

With the above4 and otherkobjects in view, the present invention consists inf thecombination'and'arrangement of parts hereinafter more fully described, illustratedV in the accompanying, drawings, and more particularly pointed out in the appended claims, it` being understood that changes may befmade'in the form, size, proportions and arrangement of thevarious parts, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings? Figure 1 isV a fro'ntelevational view of a window frame with ourwindow screen mounted thereon.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1.

Fig. 3`- is-a-view similar toFig. 2 showing the screen frameswung outwardly from the window frame.

. Fig. 4 isanenlarged fragmentaryV perspective Viewy of the Yscreen bracket, and' hanger' clip assembly, the hanger clip being shown in broken lines.

Fig. 5 is a fragmentary, perspective view showing the locking means with the finger tab swung horizontally.

Fig. 6 is also fragmentary, perspective view of the upper edge of the screen frame showing the resilient hanger clip connection.

Fig. 7 is an enlarged vertical sectional view through the ICC window and screen frame showing the screen frame raised and released from the lower edge of the window frame.

Referring now more specifically to the drawings in which we have shown one embodiment of our invention, and in which the letter W indicates a sliding transverse window frame which can be formed of metal or any other desired material, and while we have, in the instant application, shown the screen applied to a sliding transverse window frame, it will be understood that this is an exterior screen which is applicable to any type window frame.

Spaced apart L-shaped supporting bracketsV B are secured to the upper face of the window frame W by means of screws 10 or the like, the extreme end of the project'- ing leg 1.1 of each bracket being angularly disposed asy at 1'2 and said leg is formed with an elongated opening-13 thereinand for a purpose to be presently described.

A longitudinally disposed, outwardly projecting bar 14 extends across the face of the lower section of the window frame W and spaced apart passages 15 are provided in said bar for engagement by suitable locking means rvL provided on the screen frame.

The screen frame propercomprises preferably pressed rectangularlyv shapedY metallic frame F, said frame being substantially U-shaped in cross-section, with the inner leg 16 being folded over, or rolled, to form a smooth' edge, While the opposite leg 18 remains straight. A stripof screen cloth S is stretched over the opening in' the rectangular shaped screen frame F, the edges overlapping. the frame leg members 1-6, and a wire rod 19, bent and shaped to snugly t into said frame, is pressed thereinto, thus stretching the screen taut and firmly anchoring the edges of the cloth in position.

Resilient hanger clips H are mounted-on the up'per rail of the screen frame F and are formed as clearly shown in Figs. 4 and 6 of the drawing, each hanger clip com'- prising a preferably fiat strip of resilient metal, the inner end of which is'slightly rolled as at 2li for engagement by the wire rod 19, thence said strip extends horizontally and is reversely bent asiat 21, to lie in intimate facial contact with the upper leg'of the screen iframe, thence projecting outwardly beyond the front edge of the screen frame F and beingrolled to `form a tubular section' 22, thence the strip is upwardly curved as at 23, thence extending ver tically as at 24, and thence the end section is rolled downwardly to form a hook 25 for engagement with the angularly disposed section 12 -of the bracket B. A suitable space or passage 26 opens into the tubular section of the hanger so that it can be readily threaded through the elongated opening 13 and the hook 25 engages the'section 12 of the bracket. These hanger clips serve to yieldingly secure the upper end of the screen frame onthe'window frameandwhen the hook portion 25 of the hanger is threaded through the slotted opening 13 and the section 25 hooked over the angular section 12 of thebracket B, these hanger clips support the frame and yieldingly draw it inwardly into tight engagement with the window frame.

Spaced apart lock-ing members L are mounted'on'the lower rail of the screen frame, each member comprising preferably a at strip of metal 28 which extends into the frame, being bowed as at 29 to partially embrace the wire rod 19, thence being reduced in width and extending outwardly as at 30, and thence being bentdownwardly parallelito the main` body, to fformA alocking tongue 31, the leg of the lower rail 27 being notchedA asat l32 to' accommodate said tongues. These locking members and hanger clips are located when the frame is assembled and are secured in position when the ywire rod is pressed into the frame.

A linger tab 33 is hingedly secured to lthe upper end of, and forms a part of the locking means, one end of the tab and strip being rolled as at 34 to accommodate a pin zontall position `as indicated in Fig. 5 of the drawings so that they may be readily grasped to lock, unlock or otherwise manipulate the screen.

yMounting of the screen frame is a very simple operation. It' is merely necessary to thread the hook end 25 of the hanger clips through the openings 13 in `the supporting brackets B so that the lip ends hook over the legs 12 of supporting brackets. The screen frame is then forced upwardly, see Fig. 7 of the drawings, liexing the hanger clips H to permit the tongues 31 to enter the passage 15 in the bar 14, the weight of the screen frame together with downward pressure from the hanger clips serves to hold the tongues in position and the inward pressure above described provides a tight insect-proof arrangement.

From the foregoing description it will be obvious that we have prefected a very simple, practical, and relatively inexpensive insect-proof screen frame and mounting.
